4 Claims. 1

This invention relaterI to liquid applicators, and it relates more particularly to that type of applicator in which a liquid, such as paint, kalsomine, or the lire, is fed to a hollow foraminous roller, the outer surface of which is provided with a covering of textile material having a pile like face.

The principal object of the present invention is to provide a liquid applicator, of the character aforesaid, in which liquid will be uniformly fed to the surface of the roller.

A further object of the invention is to provide a device, of the character aforesaid, which may be readily dismounted for the purpose of cleansing should the same be required, and thereafter reassembled easily and expeditiously.

A further ob'ect of the invention is to provide a device, of the character aforesaid, which may be inexpensively made, but which will be simple and eflicient in its action.

The nature and characteristic features of the present invention will be more readily understood from the following description, taken in connection with the accompanying drawing forming part hereof, in which:

Figure 1 is a front elevation of a liquid applicator embodying the main features of the present invention, the same being shown connected to a pressurized supply tank of an ordinary type for feeding the liquid to the applicator;

Fig. 2 is a transverse section, enlarged, of a liquid applicator embodying the main features of the present invention;

Fie. 3 is a transverse section thereof, taken on the line 3-3 of Fig. 2; and

Fig. 4 is an enlarged detail view, illustrating a portion of the structure, which is so arranged to permit the ready separation and dismounting of the parts.

It should, of course, be understood that the description and drawing herein are illustrative merely, and that various modifications and changes may be made in the structure disclosed without departing from the spirit of the invention.

Referring now more particularly to Fig. l of the drawing, there is shown a pressurized tank 5 adapted to receive and maintain a supply of the liquid under pressure to be fed to the applicater for applying the same to a wall or other surface. The tank 5 is of any well known construction, such as is commonly used in connection with paint applicators, either cf the present type, or of the spray type.

The tank 5 is connected by a flexible supply tube 6 to a pipe 'I which extends through a han- 2 dle 8. A control valve 9 is provided in the pipe l adjacent the handle 3 for control of the feed of the liquid by the operator.

Beyond the valve 9 there is an extension I0 of the pipe line which preferably extends approximately at right angles as at I I to the axis of the handle; then parallel thereto as at I2, then being bent backwardly as at i3, which portion of the pipe line is also substantially at right angles to the axis of the handle.

The end part le of the portion I3 of the pipe line extends into the interior of the vapplicator proper, and the portion I3 forms a means for journalling the applicator at one end thereof as will be hereinafter more fully set forth.

The end of the portion I4 of the pipe line is threaded as at I5, and an extension I 6 of the pipe line is thus mounted thereon. The end of the extension I8 serves as a means for journalling the far end of the applicator proper.

This end of the applicator is provided vwith a. closure head I'I having a cylindrical boss I8 eX- tending inwardly from the center thereof into the end of the extension IS of the pipe line whereby to provide a journal for that end of the applicator. The head member I'I is entirely closed and will thus prevent leakage at the journal at that end.

The head member ITI is provided with an inwardly extending flange I9 upon which a foraminous cylinder 2li is mounted, the end thereof being held in place by means of set screws 2| passingr through the cylinder and threaded in the flange of the head member.

The other end of the foraminous cylinder 20 is mounted on an inwardly extending flange 22 of a head member 23 provided at the end of the applicator. The head member 23 is journali'ed on the portion I3 of the pipe line. This end of the foraminous cylinder 2U is secured to the head member 23 by suitable set screws 34 arranged in a manner similar to the set screws 2l at the other end of the cylinder.

Upon the outer face of the foraminous cylinder 2t there is mounted a textile covering sleeve 24 having a pile face 25 which may be made of a suitable grade of velvet carpet of sufficient porosity to permit the liquid to pass therethrough.

At the point `where the extension IB of the pipe line is threaded on the end of the portion I4 of the pipe line, there is thus provided a shoulder 25 upon which a disc or washer 21 is mounted. This disc or washer 2l is of a diameter less than the internal diameter of the foraminous cylin der 2B.

A coil S13-ring 28 is mounted on the pipe I4 and bears at one end against the Washer 2, and at its other end against a dished Washer 38, the periphery of which bears against a sealing Washer 29, preferably made of leather or the like, and impels the same against the inner face of the head member 23.

The central portion of the sealing washer 29 is formed to extend inwardly, as at 3l, and lap against the outer surface of the pipe I3 to prevent leakage at the point where the head inember 23 is journalled on said pipe.

The inner end of the pipe Iii within the applicator is provided With a series of holes 32, and likewise the extension member IB of the pipe line which is threaded on the end of the pipe I@ is provided with a series of holes '53, the foregoing arrangement being such that when the liquid is fed through the pipe I3, the liquid will pass through the aforesaid holes 32 and 33 to the `interior of the applicator, the operator actuating thevalve Q Whenever it becomes necessary to replenish the supply of liquid within the applicator.

It should, of course, be understood that it will not ordinarily be necessary to keep the applicator filled with the liquid, as the rolling' action thereof will, during the operation, cause the liquid to be `distributed through the foraminous cylinder 2i! to the pile face 25 of the textile cylinder 2d which 'covers the same.

The operation of the device will, of course, be readily understood. The liquid supplied is forced, in the usual manner, from the interior of the tank 5 through rthe exible tubing 5 to the pipe l which passes through the handle 8 of the applicator, the liquid being controlled by the operator 'by means of the valve 9. Whenever the valve Si is opened, a p-ortion of the liquid will pass through the parts Ill, II, I2, I3, Ill and I5 of the piping, to the interior of the applicator, passing through 'the holes 32 and 33 in the pipes la and It, and being distributed over the interior of the forami- Vnous cylinder 2D, and thence fed to the porous envelope 24 provided by the textile cylinder 24 mounted on the exterior of the surface of said *foraminous cylinder.

It is, of course, Well understood that the materials, 'commonly used in applicators of the character aforesaid, are of such nature as to ouickly harden and clog up the various parts and thereby ,render the applicator inoperative, but in an applicator, of the character herein described, it is usually only necessary to rst remove the textile cylinder 24 and cleanse the same with a suitable solvent, depending on the particular liquid used,

and Vthe interior parts may ordinarily be cleansed "by1the passage therethrough .of a small quantity of a suitable solvent.

Should, however, a more complete cleansing of .the parts be required, this may be accomplished by the mere removal of the set screws 2 I, Whereupon the various parts of the applicator may be .removed .and separated from each other for a thorough .and complete cleansing.
